Ekishin (亦信) is a diligent and serious guard living and working in Genei Palace in En.[1]
When Enki decides to meet Kouya for the first time in many years, Ekishin is assigned to accompany the Taiho in case something should happen. Though Enki and Ekishin do not anticipate anything will occur, Kouya coerces Enki into becoming a hostage for Atsuyu when Kouya threatens to have an infant girl devoured by his demon beast. Ekishin is slain attempting to defend Enki and prevent the kirin's abduction.
